Significance of enhancement technique in segmentation of image and signal : a review of the literature

الملخص EN

From the last 70 years, there is continuous development in the field of digital image processing such as geology, biology as well as in medical fields.

Solving many problems in the case of numerous application image processing plays an important role.

Recently, wireless communication has been a dominant medium.

When a signal or image is transmitted via the wireless environment, the quality of the image or signal gets degraded.

It is the biggest issue.

This happens because of acquisition and color space conversion.

Hence, priority is given to enhance the quality of the image or signal.

Enhancement is the process responsible to enhance the quality of the signal.

In this paper, we focused on various enhancement techniques for image and signal enhancement.

Furthermore, this study put down the result for various enhancement techniques for improvement in the image.

Theoretically, the signal enhancement was discussed shortly.
